IMPROVEMENT IN TIPS FOR GAS-BURNERS.

TO ALL WHOM IT MAY CNGERN:

Be it known that I, REINIIQLD LANSTROM,`of Cincinnati, Hamilton county, and State ofOhio, have invented a new and improved Tip for Gas-Burners, denominated Soapstone Tip for Gas-Burners, of which the following is a full and clear description, reference being had to the accompanying drawings, maliing part of this specification.

My invention relates to the application and construction of soapstone tips for gas-burners, whereby the uniform iicw of gas is not liable to be checked, as is the case from corrosion in the iron or metal tips.

Figure 1 is a perspective view of my improved tip detached from the stem of the burner.

Figure 2 represents a longitudinal section of a gas-burner, including my improved tip, constructed of' soapstone.

Figure 3 represents, in perspective, a bar of soapstone from which my improved tip is being formed.

A is the stem of an ordinary gas-burner, having a cylindrical opening longitudinally through its entire length. The large end a is tapped to the gas-pipe. The smaller end b has a socket,- which terminates with the shoulder c. B indicates my improved tip, in shape similar to those made of metal or lava. The thread upon the neck eZ, usually met with in the metal tips, is dispensed with. The tip B is perforated to the bulb-end c, which is slotted. The neck d is tted securely in the socket of' the small endb of the'stem, the shoulder c oi' the tip being brought into close contact with the extreme end b, white lead or other suitable material being employed to set and pack the tip in its place. I l

In the manufacture of these tips, I take, in the rst place, a strip of the soapstone, square in section, as indicated in fig. 3, place it in a lathe, turn the tips from the strip, commencing at one end, as illustrated at 1 in iig. 3. The tips may be detached from the strip as rapidly as turned off by causing a rapidly-revolving saw to pass between them and the strip. Then, by means ct' a drill, the perforation from the neck-end to the bulb e is rapidly performed. A thin disk-saw inishes the operation by clotting the bulb e, when the tip may be connected, as above described, with the shank of the burner.

The durability of the material of which I construct'the tip strongly recommends it usan article of manufacture. Instead of being Vinjured bythe intense heat resulting from the combustion, the improved tip,

hardens, presenting a surface nearly as tough as steel. What I claim as new, and of my invention, is-

1. The application of soapstone in the construction of tips for gas-burners, when constructed and applied1 substantially as above described and shown.

2.,'1 claim a new article of manufacture in the soapstone tips for gas-burners herein described.
